PATENT RUSSELL PEARCE, 0F TECCAR-TNEY, PENNSYLVANIA.

CARBIDE-LAIVIP CLEANER.

Application led March. 12, 1921.

To oiZZ whom t may concern:

Be it known that I, RUSSELL PnAnoE, a citizen of the United States, residing at McCartney, inthe county of Clearfield and State of Pennsylvania, have invented new and useful Improvements in Carbide-Lamp Cleaners, of which the following is a specii'ication.

This invention relates to cleaning devices, and more particularly to a carbide lamp cleaner.

One of the main objects of the invention is to provide simple and eiiicient means for scraping and cleaning the interior of the carbide tank commonly employed in miners carbide lamps so as to prevent corrosion of the tank and permit ready emptying of the same. A further object is to provide a cleaner which is permanently associated with the tank and is so positioned as to be within and protected by the body of the lamp when the tank is applied. Another object is to provide a cleaning device which may be readily grasped and operated. Further objects will appear from the detailed description.

In the drawings:

Figure 1 is a side view of a carbide lamp of standard type, partly broken away, with the cleaning device applied.

Figure 2 is a vertical sectional view through the tank.

Figure 3 is a section taken substantially on line 3-3 of Figure 2.

The device is adapted to be used in connection with a carbide tank a of known type which is detachably secured in the lower portion of the body b of lamp B by means of screw threads or in any other suitable or preferred manner. The cleaning device comprises a strip l of sheet steel or other suitable material which is flat in crosssec tion and is of suitable guage and temper to provide a rigid scraping device. This strip is pivotally secured at its inner end, at 2, to bottom 3 of tank a. At its outer end the Serial N0. 451,79.

strip is turned upwardly substantially at right angles and is bent to conform to the contour of the peripheral wall and upper portion of the tank, this strip being in tight contact with the inner face of the peripheral wall of the tank and with the bottom of the tank. The strip projects above the top of the tank and has its upper end portion la of eoncavo-convex cross-section with its concaved face directed inwardly of the tank. This facilitates gripping of the upper end of the strip for rotating the same about pivot 2, and the outer conveXed surface of portion 1ZL effectually prevents binding of the strip on the upper edge of the tank thus facilitating operation of the device. By turning strip l about pivot 2 the inner face of the peripheral wall and the bottom .of the tank is effectively scraped so as to remove all materials adhering thereto, and this material may be readily emptied from the tank leaving the inner surface of the same clean and bright. This serves to effectually prevent corrosion of the tank and also eliminates probability of injury to the tank due to scraping and beating of the same such as is frequently done to loosen the sludge which adheres to carbide tanks not provided with cleaning devices. The device may also be utilized for agitating the carbide in the tank so as to facilitate generation of gas thus effecting a saving' in the carbide used.

What I claim is In combination with a carbide lamp including a body and a carbide tank detach- RUSSELL PEARCE.
